1. An in-vehicle relay apparatus to be provided on a roof of a vehicle, comprising:
a first connector to which a power line and a communication line provided on one pillar of the vehicle are to be connected;
a second connector to which a power line and a communication line provided on a different pillar from the one pillar are to be connected;
a branch line connector to which power lines and communication lines extending from a plurality of in-vehicle devices provided on the roof are to be connected;
a branching portion that branches a single wire system into power lines that are connected to the branch line connector, the single wire system being a system in which the power lines respectively connected to the first connector and the second connector are integrated into one system; and
a relay unit configured to relay data passing between the communication lines respectively connected to the first connector and the second connector and the communication lines connected to the branch line connector,
wherein two power supply apparatuses are installed in the vehicle, the power supply apparatus to which a voltage is applied via the power line connected to the first connector and the power supply apparatus to which a voltage is applied via the power line connected to the second connector being different from each other, and
the in-vehicle relay apparatus is to be connected to a relay device installed in the vehicle, via the communication line connected to the first connector and via the communication line and an in-vehicle apparatus connected to the second connector.
